The invention relates to the devices for creating acoustic vibrations in flowing liquid medium, in particular to the rotary-pulse apparatuses, which can be used for dispersion, emulsification and mass exchange in chemical, oil, mining, food and other industries. As a result, the invention solves the problem of high performance of rotary-pulse apparatus due to substantial increase of amplitude of pulsations. To this end, a narrowed portion of a Venturi tube is designed as a solid cylinder, while the ratio of the diameter of the outlet section of Venturi tube to the diameter of its narrowed section is equal to the 3.8-4.5, the opening angle of the diffuser part is 15° -30°, and on a pressure line upstream of the Venturi tube and on an outlet pipe control chokes are installed. |
